Supply chain and procurement
How to buy well as a small business: choosing and managing suppliers, understanding where your supply chain is fragile, negotiating sensibly, and keeping the goods and services you depend on arriving on time and on budget.
- Specify: Define what you need, how much, by when, to what standard.
- Source: Find and compare suppliers; agree price and terms.
- Order: Raise a purchase order so both sides have one record.
- Receive: Check quantity and quality against the order.
- Pay: Match invoice to order and receipt, then pay on terms.
- Review: Track supplier performance and renegotiate.
For most small businesses, what they buy is the biggest cost after wages, and for retailers, wholesalers, manufacturers and trades it is usually the biggest cost of all. Yet purchasing is often done reactively: whoever notices stock is low calls the usual supplier, agrees whatever price is quoted, and the invoice is paid when it arrives. Nobody is accountable for the total.
Procurement is the discipline of buying deliberately. Supply chain management is the wider view: understanding every link between your suppliers’ suppliers and your customer, where delays and risks sit, and how to keep goods and services flowing. For an Australian SMB this does not require a procurement department. It requires a few habits, a short supplier list you actively manage, and a clear view of which purchases really matter.
Why it matters
A few percentage points saved on your largest purchases often adds more to profit than a sizeable increase in sales, because the saving goes straight to the bottom line. Just as important is resilience: Australian businesses are often at the end of long international supply lines, and a single supplier failure, shipping delay or freight cost spike can stop trading. Knowing your exposure before it bites is the point of managing the supply chain rather than just buying from it.
Know what you buy and from whom
Start with a spend analysis: pull twelve months of supplier payments from your accounting software and group them by supplier and category. Most owners find that a handful of suppliers account for most of the money, a long tail of small suppliers accounts for most of the admin, and a few categories are bought from several suppliers at different prices for no good reason.
This list is your procurement agenda. The big suppliers are where negotiation and relationship management pay. The long tail is where consolidation and simple purchasing rules save time. The duplicated categories are the quickest wins.
- Export supplier payments for the last twelve months and sort by total.
- Group into categories: stock, materials, freight, subcontractors, software, utilities, consumables.
- Flag categories bought from more than one supplier and compare unit prices.
- Note how many suppliers make up the top four-fifths of spend; that is your core list.
Treat different purchases differently
Not every purchase deserves the same attention. A useful way to sort them is by two questions: how much do we spend on it, and how hard would it be to replace the supplier? High-spend, hard-to-replace items are strategic: a key ingredient, a specialised component, the one freight company that services your region. They need relationships, contracts and a plan B. High-spend but easy-to-replace items are where competitive quoting works. Low-spend, hard-to-replace items are bottlenecks that can stop production over a trivial part, so hold buffer stock. Low-spend, easy-to-replace items should be bought with minimum effort.
This simple sort stops the common mistake of spending hours haggling over consumables while leaving the one supplier who could shut you down unmanaged.
- Leverage: Big spend, many suppliers: run competitive quotes and negotiate hard.
- Strategic: Big spend, few suppliers: build the relationship, contract, and hold a plan B.
- Routine: Small spend, easy to replace: automate and consolidate, minimise effort.
- Bottleneck: Small spend but could stop you: hold buffer stock and find an alternative.
Choose and manage suppliers on more than price
Price is the easiest thing to compare and often the least important. Reliability of delivery, quality consistency, lead time, minimum order quantities, payment terms and how the supplier behaves when something goes wrong usually matter more over a year. Ask for references, start with a trial order, and check basics such as an ABN, insurance where relevant, and whether the supplier is itself dependent on a single source.
Once a supplier is on your core list, manage them. Agree how you will measure them (on-time, in-full delivery and defect rate are the standard pair), review the numbers quarterly, and raise problems early. Good suppliers prefer a customer who is organised and pays on time; it is often the basis for better pricing and priority when supply is short.
Build in resilience before you need it
Supply chain risk for Australian SMBs typically comes from distance and concentration: a single overseas manufacturer, one shipping route, one freight company or one import agent. You cannot remove the risk, but you can reduce it. Qualify a second supplier for strategic items even if you give them a small share of orders. Hold safety stock on bottleneck parts. Know your suppliers’ lead times and watch for drift. Keep a short written plan for what you would do if your top three suppliers each failed tomorrow.
Resilience costs a little margin in normal times. It pays for itself the first time a shipment is delayed by six weeks and your competitor has nothing on the shelf.
How to take control of purchasing
- Analyse twelve months of spend Group supplier payments by supplier and category. Identify the core suppliers and duplicated categories.
- Sort purchases by spend and risk Strategic, leverage, bottleneck or routine. Decide how much attention each group gets.
- Consolidate the long tail Reduce the number of small suppliers and set simple rules for who may buy what, up to what value.
- Quote competitively where it pays For high-spend, easily replaced items, get at least three quotes and compare total cost, not unit price.
- Use purchase orders Every order gets a PO so quantity, price and date are agreed in writing before goods arrive.
- Check deliveries and match invoices Compare delivery to PO, and invoice to both, before paying. Query discrepancies promptly.
- Review core suppliers quarterly On-time delivery, defects, price movement. Raise issues early and renegotiate annually.
- Qualify a backup for strategic items Even a small share of orders keeps the alternative real.
Real-world example
An Adelaide furniture maker rethinks its timber supply
Gumtree Joinery makes custom furniture with a team of seven. A spend analysis shows annual purchases of about $620,000, with timber from a single interstate mill making up roughly $280,000, hardware and finishes about $110,000 across nine suppliers, and the rest spread over freight, tooling and consumables. The owner realises that a mill shutdown or freight disruption would stop the workshop within two weeks.
She classifies timber as strategic, qualifies a second mill in Victoria for about a fifth of her volume, and negotiates a twelve-month price agreement with her main mill in exchange for committed monthly volume and payment within fourteen days. She consolidates hardware from nine suppliers to three, which lifts her order values enough to earn trade pricing roughly 8 per cent lower. The combined effect is around $15,000 a year in savings on hardware and a timber supply that would survive either mill failing, for the cost of a slightly higher unit price on the backup volume.
Common mistakes
- Buying on unit price alone Freight, minimum order quantities, payment terms, quality and reliability all change the real cost. Compare total cost of ownership.
- Single-sourcing strategic items One supplier, one route or one agent for something you cannot trade without is a business-ending risk waiting for a trigger.
- No purchase orders Without a written order, disputes over quantity, price and date come down to memory. A PO takes a minute and settles most arguments.
- Paying invoices without matching Short deliveries, price creep and duplicate invoices slip through when nobody checks the invoice against the order and the receipt.
- Never reviewing suppliers Long relationships drift: prices rise quietly and service slips. An annual conversation with data keeps both sides honest.
KPIs to track
- Supplier on-time, in-full rate Share of deliveries that arrive when promised with the full quantity. Track per core supplier; aim high and watch for decline.
- Purchase price variance How actual prices paid compare to agreed or budgeted prices. Rising variance signals price creep.
- Spend under agreement Share of total spend covered by negotiated terms or contracts rather than ad hoc buying.
- Supplier concentration Share of spend with your single largest supplier, and how many strategic items have only one source.
- Days payable outstanding Average days you take to pay suppliers. Use the terms you negotiated, but pay on time to protect the relationship.
Frequently asked questions
Is it worth negotiating with suppliers when I am small?
Yes. Most suppliers have flexibility on terms, freight or volume pricing, especially for customers who order predictably and pay on time. Consolidating your orders with fewer suppliers increases your leverage.
Should I always get three quotes?
For high-spend items you can easily source elsewhere, yes. For strategic suppliers, periodic benchmarking is more useful than constant re-quoting, which damages the relationship you depend on.
How much safety stock should I hold for imported items?
Enough to cover the realistic worst-case delay, not the average lead time. If a shipment normally takes six weeks but has taken twelve, your buffer should reflect twelve. Inventory management techniques help size this.
What should be in a supplier agreement?
Prices and how they may change, lead times, minimum orders, quality standards, payment terms, what happens when deliveries are late or defective, and how either side ends the arrangement. Have significant agreements reviewed by a legal adviser.
